Assuming you're a new flyer, as an instructor, most new flyers that show up at our field with ARF planes they've assembled are mostly well finished, but do need some additional work. Always have an experienced flyer/instructor go over your plane with you pre-flight. You'll learn new things. Examples of things we've had to fix are center of gravity, control surface angles, loose torque rods in ailerons (very common), reversed controls, fuel lines reversed, batteries not secured, loose wheel collars, etc. These were all easily repaired at the field prior to flight. Only had one case where we wouldn't fly the plane because the owner had not fixed the battery in place, and we didn't have materials available to properly install it. (Now I carry double sided foam tape in my field box).

Good Luck!
